The Alvin Rotatrim 38" technical trimmer works for all of your tough framing needs and is able to accommodate extra thick and dense materials as well as thinner materials, substrates, and films to make an effective framing trimmer. This diversity makes it an excellent trimmer for all around use whether you need it for lighter projects or heavy duty framing needs. Excellent for use in custom framing, this trimmer features heavy duty supports and a sturdy cutting blade ensure long use and low wear while a self sharpening cutting wheel handles all levels of cutting projects. The steel guide bar and easy to release clamping bar ensure even and precise cuts. Three, rubberized pressure rollers ensure excellent clamping during the cutting process to stabilize materials. This trimmer cuts in both directions for your ease of use in handling large projects. The 11" baseboard allows cutting of smaller materials but can also be used with baseboard extension rods to support larger materials with a total depth of 28". The Rotatrim guarantee ensures that this product is free of manufacturer defect for five years, excluding cutting blades and rubber pieces that encounter wear and tea. Improper use, handling, or storage voids this warranty.
